I tried a lot already. No success to get the sound working on my old
maxdata laptop.

This is what I got:

Please let me know if/what further information I should provide to
give you a better understanding in what is wrong.

If bios did not setup pin default of alc880 codec, you need to find out
the pin of hp and mic jacks by hdajacksensetest , speaker and internal mic
need to find out by trial and err with hdajackretask

This is the output of hda-jack-sense-test. What do you recommend?

Post the output of alsa-info.sh
You have to use
hdajacksensetest -a
It gives the same output.
Did you plug and unplug headphone or mic jack during test ?
No.
you have to post output of

hdajacksensetest -a

when you plug headphone , unplug headphone , plug mic and unplug mic
...
Since pin default of all pin complex are zero which is Line Out
It is a laptop. I want to use its internal speakers, if that info helps.
All pins have to be fixed by hdajackretask

Any redundant pins must set to [N/A]
alc880 only have models for desktop

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/log/sound/pci/hda?qt=grep&q=alc880
In the past, there was a "test" model which setup all pins

https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pc...

you can try

options snd-hda-intel model=6stack-dig

to find out whether the speaker is node 0x14 and Headphone and 0x1b

you have to manually find front mic, rear mic and line in is your laptop
internal mic and mic jacks

Do windows driver contain info about the pins since it also need to setup
the pin complex too ?
